Our Story

Jonas Energy Solutions is a fourth-generation, family-owned company in Lake County, CA. We take great pride in our longstanding history of community involvement throughout Lake County, Napa County, and Mendocino County. Founded by Jim Jonas, our natural progression over the years has included Jim Jonas’ transition from his father’s Union Oil distributorship—operating in Lower Lake since 1935—to HVAC and solar energy solutions, in addition to whole-house generator services and home battery services.

Our team has accumulated a great deal of knowledge over the years about what works and what doesn’t for our unique climate. Our products and services have evolved to reflect this. We are green-energy conscious and focused on energy solutions and self-sustaining systems for homes and businesses.

For well over four decades, we’ve continually educated ourselves and our staff so we have the most knowledge of changing needs. With ongoing, comprehensive training programs and specific policies and procedures, you can rely on Jonas Energy Solutions for service held to a high standard.
